  • Publication number: 20040220542
    Abstract: An apparatus and method for preventing free flow through an infusion set utilizes an occluder disposed within the infusion set to selectively prevent flow therethrough. The occluder may be responsive to a pressure differential within the infusion set or may respond to compression of the infusion set. When a pair of occluders are used in sequence, an in-line pump may be formed.

  • Patent number: 6749591
    Abstract: A pinch clip occluder system for infusion sets includes a housing and a clamp movably disposed within the housing to selectively occlude an infusion set. The pinch clip nests in an adapter placed on an enteral feeding pump such that when the pinch clip occluder is properly position, flow is allowed through the infusion set, but when the pinch clip occluder is not properly positioned in the adapter, flow through the infusion set is prevented.

  • Publication number: 20020091365
    Abstract: An enterostomy device for providing fluids and nutrients through a stoma formed through the abdominal wall of a patient is described. The enterostomy device, which may be configured as either a gastrostomy device or a jejunostomy device, comprises a low-profile retaining member which is configured to be unobtrusively positioned within the stomach or the intestine, and which is configured to provide sufficient surface area for contacting the stomach or intestine to prevent unintentional removal or release of the enterostomy device from the patient. The enterostomy device is also structured with a low-profile port hub for facilitating the inflation of the retaining member and feeding and venting through the stoma.

  • Patent number: 5810323
    Abstract: A pinch clip occluder for infusion sets is disclosed including a housing and a clamp movably disposed within the housing to selectively occlude an infusion set. In one embodiment the clamp has at least one arm which moves between first and second positions to pinch closed a silicone tube of the infusion set unless the pinch clip occluder is held in an open position by the user, or placed in a receptacle which will hold the pinch clip occluder in an open position. In another embodiment a plunger is disposed so as to intersect a passage passing through the housing. As the plunger is selectively moved between first and second positions, the flow through a tube in the passage is selectively controlled. Such an arrangement prevents a free-flow condition from occurring through the infusion set.

  • Patent number: 5789675
    Abstract: A disposable fluid level sensor of the present invention determines the level of fluid in a container. A flex circuit sensor is coupled to a processing module having a power supply, the flex circuit sensor being mounted at a selectable location by an adhesive patch which holds the sensor flush against the container. The processing module hangs from the flex circuit, and provides a human perceptible indication, such as a flashing light or an audible alarm, when the fluid level drops below a desired point as determined by the sensor. The sensor detects the change in fluid level by transmitting an electromagnetic signal and determining whether there is a change in reflected energy.

  • Patent number: 5438868
    Abstract: A noninvasive ultrasonic liquid level indicator for indicating the level of a liquid in a reservoir is disclosed which comprises an ultrasonic transducer assembly, structures for holding the transducer assembly in a dry coupled attachment with the reservoir at selectable locations against an exterior surface of the reservoir, and a monitor for revealing a change in liquid height. The transducer assembly conveys signals regarding changes in liquid height to a monitor which warns the user in time to add more liquid or replace the reservoir before the liquid supply "runs dry." The manners for holding the assembly in place include, but are not limited to, a strap, a clamp, or adhesive material, such as tape. These allow the user to selectively place the transducer assembly along the reservoir at the desired triggering point.
